Numbers

implied type	let var = 12;
assigned type	let var: i8 = 12;
type suffix	let var = 12i8;

Integers

• signed integers are positive, and use all available bits
• unsigned integers range is split in two, can be positive/negative
• use radix to calculate max size that can be accomodated with b bits $2^{b}$

// signed integers, by bit-size
i8
i16
i32
i64
i128

// unsigned integers, by bit-size
